METHOD AND DEVICE FOR FORMING PRODUCT STACKS OF FOLDED OR UNFOLDED PRODUCT BLANKS OF PAPER CELLULOSE OR THE LIKE

摘要

The method of forming the product stacks 2 of the folded or unfolded product blanks 4 in which the product blanks 4 to be stacked are continuously supplied to the stacking surface 15 and arranged upright thereon is particularly simple and reliable. In this way, it is intended to keep the stress on the material to be treated low so that product blanks 4 made of chemical pulp or the like can also be reliably processed, while allowing high flexibility, especially in the formation of product stacks 2. To this end, the rear walls of the product blanks 4 are temporarily supported in accordance with the invention by the channel walls 20 of the discharge channels 17, wherein when the product blanks 4 are laid, the separating element 22 Is inserted between two successive product blanks 4 so that the product stack 2 to be formed between the separation element 22 and the channel wall 20 has a predetermined number of product blanks 4 After insertion of the element 22, the channel wall 20 is opened so that the product stack 2 formed between the separating element 22 and the channel wall 20 can be inserted into the discharge channel 17.
